Barbus is demonstrating its restoration expertise by showing off several vintage Mercedes-Benz models.

A “6-star restoration” from Brabus takes up to 4,000 man-hours and some of the best examples were on display at the 28th Techno-Classic in Essen. There were two 300 SLs (one Gullwing and one Roadster), two 280 SL Roadsters (W113 Pagonda), two 280 SE 3.5 Cabriolets (W111), and a 600 Pullman from 1967. Brabus was kind enough to release an extensive gallery of all these cars, including other vintage and classic Mercs that have received or are about to get Brabus’ very best TLC.

Brabus has its own vintage car division headquartered at a facility opened in 2014 in Bottrop, Germany where there’s a showroom and a workshop for restoring and servicing various Mercedes-Benz models. With around 21,500 square feet (2,000 square meters) of usable space, the Brabus Plant 4 is all about restoring vintage and classic cars to their former glory and the extensive work backed by a two-year warranty with unlimited miles.

Each car that goes through a restoration process is disassembled “to the last nut and bolt” and then all of the components are inspected and catalogued. Unserviceable parts are thrown away while the others that can be reconditioned are brought back to life. The original paint is removed from the body shell which then is reconditioned and receives a catalytic dip primer coating.

Extensive work also goes into rejuvenating the interior cabin which is restored to the exact same specification as the original. It’s the same story with the engine and gearbox which are both overhauled, while the suspension and brakes are entirely replaced with new parts to ensure safety.

You can imagine a full restoration process doesn’t come cheap, but looking at these images, we feel it’s worth every penny.
